Vadim Makhorov and Vitaly Raskalov sent a shockwave through the Internet on February 12, 2014 when they posted a video of themselves climbing the Shanghai Tower. The 2,073-foot (632-meter) Shanghai Tower when completed will be the second tallest building in the world after the Burj Khalifa in Dubai.

Check out these incredible photos that the pair took from the top of Shanghai Tower, and some other snaps of Shanghai. All photos courtesy Vadim Makhorov and Vitaly Raskalov of On the Roofs and republished with permission.
